Oil (density = 910Kg/m3 and viscosity 3.1 x10-3 Pa-s) is pumped from an open tank to a pressurized tank held at 400KPa gauge. The oil is pumped from an inlet at the side of the open tank through a line of commercial steel pipe (inside diameter 0.8m) at a rate of 5x10-3 m3/s. The length of the straight pipe is 150 m, and the pipe contains 4 (90-degree) elbows and two globe valve half open. The level of the liquid...

1 A pump delivers water from the lower reservoir to the upper reservoir at a rate of 60 L/s. Both the suction and discharge pipes are DN 150 schedule 40steel pipe. The length of the suction pipe leading to the pump is 3.5 m, and 7 m of discharge pipe extend from the pump outlet to the upper tank. There are three standard 900 elbows and a fully open gate valve. The depth of the fluid level inside the lower...

QUESTION 9 15 marks Water is pumped at a constant rate of SOL/s through the system illustrated in the figure below. The water is pumped from a large reservoir into an elevated pressurized tank that is used as part of an emergency firefighting system. The head loss in the 150mm supply line to the pump is 0.8m. The head loss in the s200mm delivery line and elbow connectors from the pump to the tank is 4.5m. The pump has an...

8-C) As shown below water is pumped and sprayed through a nozzle into the atmosphere at 20 m/s at an elevation 10 m above the reservoir surface. The mass flow rate is 40 kg/s and the volumetric flow rate is 0.040 m3/s. The large diameter inlet pipe total length is 50 m. The pump effidency is 65%. The longer smaller diameter pipe leaving the pump is 200 m in total length. The pipes have different diameters as indicated below. The...

Erample 12.7. Water is being pumped at the rate of 20 l/s to an overhead tank through a 15 cm diameter 300 m long delivery pipe. In the tank pipe discharges freely at height of 15 m above the pump. If head loss h = 0.03 for pipe, determine the pressure developed by the pump on its delivery side and power required to lift the water. Assume first 285 m of pipe is horizontal and rest is vertical.
Underground water needs to be pumped into a pool
The school decides to create a new Fluids test facility on the lab building roof. Underground water needs to be pumped bu a 7373% efficient 5.05.0-kW submerged pump to the facility, which has a free surface h=3030 m above the underground water level. The diameter of the pipe is 7.07.0 cm on the intake side and 5.05.0 cm on the discharge side.Assume the elevation difference between the pump inlet and the outlet and the effect of the kinetic energy correction factors to be negligible.a) Determine the maximum...
